I've applied lots of what I learned here to my design,
and I've got the PWM/pitch interaction down to what I think is an acceptable minimum. Anyways, it's nothing special, but I've started a <a href="https://www.muffwiggler.com/forum/viewtopic.php?f=17&t=225670" class="">build thread over at muffs</a>, for anyone who needs yet another low cost 3340 vco. I need several, so thought I may as well go public in case anyone else does, too. I'll be using JLCPCB assembly for all the resistors and caps, and the rest will be through hole at home. I have lots of as3340s, so can include with the PCB if anyone needs. 3340 is running on +10/-5, so the circuit should be at home in 12v or 15v setups. I'm in Yukon, Canada.</div><div class="">Thanks,</div><div class="">Colin<br class=""></div></div><br class=""><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri, Jan 3, 2020 at 12:39 PM David G Dixon <<a href="mailto:dixon@mail.ubc.ca" class="">dixon@mail.ubc.ca</a>> wrote:<br class=""></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
